A lighter row of pixels below the tab bar bottom border and above Dolphin's darker view

SUMMARY
Tab bars have a row of pixels right below the bottom separator that's colored with the color of the tab bar background, rather than the below content background, which sort of creates the impression of a double-thick line in some cases. I suggest to just shave off this entire row of pixels completely rather than trying to figure out the content area's color.

STEPS TO REPRODUCE
1. Open Konsole or Dolphin
2. Open some tabs
3. Zoom in

OBSERVED RESULT
Just below the tab bar bottom border, there seems to be another row of pixels that doesn't fit the color of the rest of the window below it.

EXPECTED RESULT
Tab bar bottom border and then  the content directly
